They just haven't developed enough yet for that sweet smell, no worries man. Look for that odor to kick up in a couple weeks. Mine usually really start smelling at 6 weeks.
...but that's my strain, and just an opinion that ain't worth much. Hey...Did a couple of your leaves touch the light? Is that what happened to that leaf in the first pic?
OMB Reviewed by OMB on . Weed plant has no smell? Hi, I'm 4 weeks and 5 days into flowering (13 weeks and 1 day) from the very start and i was wandering weather my plant should have that characteristic weed smell as it doesn't really smell particularly strong except when you sniff the bud directly over it close up but even then after the third or fourth sniff i can't smell anything. Could it just be because i'm used to the smell or should the smell be strong enough that you can't forget that its there or used to it if you know what i mean. Rating: 5
